GMRT study of X-shaped radio sources
Dharam Vir Lal, A. Pramesh Rao, Martin J. Hardcastle +5
Context. The nature of X-shaped sources is a matter of considerable debate in the literature: it has even been proposed that they provide evidence for black-hole-mergers/spin-reori…
Chandra evidence for AGN feedback in the spiral galaxy NGC 6764
J. H. Croston, M. J. Hardcastle, P. Kharb +2
We report the Chandra detection of X-ray emission spatially coincident with the kpc-scale radio bubbles in the nearby (D_L ~ 31 Mpc) AGN-starburst galaxy NGC 6764. The X-ray emissi…
Evidence for Non-Hydrostatic Gas Motions in the Hot ISM of Centaurus A
R. P. Kraft, M. J. Hardcastle, G. R. Sivakoff +16
We present preliminary results from a deep (600 ks) {\em Chandra} observation of the hot interstellar medium of the nearby early-type galaxy Centaurus A (Cen A). We find a surface…
A Transient Black-Hole Low-Mass X-Ray Binary Candidate in Centaurus A
Gregory R. Sivakoff, Ralph P. Kraft, Andrés Jordán +14
We report the discovery of a bright transient X-ray source, CXOU J132518.2-430304, towards Centaurus A (Cen A) using six new Chandra X-Ray Observatory observations in 2007 March--M…
A Radio Through X-ray Study of the Jet/Companion-Galaxy Interaction in 3C 321
Daniel A. Evans, Wen-Fai Fong, Martin J. Hardcastle +6
We present a multiwavelength study of the nucleus, environment, jets, and hotspots of the nearby FRII radio galaxy 3C 321, using new and archival data from MERLIN, the VLA, Spitzer…
Globular Clusters and X-ray Point Sources in Centaurus A (NGC 5128)
Kristin A. Woodley, Somak Raychaudhury, Ralph P. Kraft +6
We detect 353 X-ray point sources, mostly low-mass X-ray binaries (LMXBs), in four Chandra observations of Centaurus A (NGC 5128), the nearest giant early-type galaxy, and correlat…
